Application filed October 20. 1904. Serial No. 229,220;

' To all whom it may concern:

Be it known that I, JULIUS OLESCHAK, a subject of the Emperor of Austria-Hungary, residing at Philadelphia, in the county of- Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention relates to that class of locks in which the bolt is operated by means of a rotary cylinder containing. a series of transverse tumblers which are adapted to lock the cylinder by the engagement of the ends of the tumblers with holes in an outer cylinder or casing.

The object of my invention is to improve the construction and cheapen the cost-of this class of locks by making each of the tumblers of a single piece of wire, which is bent or folded in the form of an inverted S. v

The nature of my improvements will be more fully understood by reference to the accompanying drawings, forming part of this specification, in which Figure 1 represents a perspective vievhiof 1g. 2 illustrates a vertical section taken transversely through the cylinder on a line 2. 2 of Figs. 1 and 4, showing the construction and arrangement of one of the tumblers. shows a similar section on a line 3 3 ofFigs. land 4, showing the arrangement of the tumbler adjacent to that shown in Fig. 2. Fig. 4 illustrates a transverse section taken on the line 4 4 of Fig. 2. Fig. 5 illustrates a detached perspective view of the cylinder, and Fig. 6 is a detached perspective view of one of the tumblers and spring.

Referring to the several parts of the drawings by letters, A represents the shell or casing of the lock, to which is fastened a cylinder A, provided with a series of holes or openings a a, &c., to receive the ends of a series of tumblers.

A is a disk-shaped enlargement formed at' the base of the cylinder A, serving as a flange for screws 0 a,'by which the portion A is united to the cylinder A.

B is a rotary cylinder containing a series of wire tumblers C and provided with holes- B B to receive the projecting ends of these tumblers. The cylinder B has a detachable portion D, which after the insertion of the tumblers G is secured in place by a screw (1.

Fig. 3 I

The tumblers C are formed of steel wire, which is cut the requisite length and then bent by suitable dies in the form of the letter S, the projecting ends Q C of which are adapted to the holes B B of the cylinder B. The

oppositely-disposed projections C of the tumblers are provided with spiral springs E, which hear at one end against the bent portion of the tumbler and at the other against the inner wall of the tumbler-cylinder. The disposal of the tumblers C within the cylinder is such that when the first is pressed downward by its springthenext in order will be pressed upward, and, moreover, while the spring on the first tumbler is located at the left of the tumbler the next in order is located permits'the use of a key having unhke undulating sides, which practice makes the tu m- -blers much more difiicult to manipulate without the aid of a properly-fitted key than where the tumblers are arranged to be operated upon from one side of the key only.

F-is the bolt, which is conventionally operated bythe cylinder B, and G (see Fig. 4) is the key for manipulating the tumblers.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A look comprising a fixed, and a movable cylinder, a plurality of tumblers guided in holes in themovable cylinder and adapted to register with corresponding openings in the fixed cylinder, each of the tumblers being formed of a strip of metal bent or folded to form two loops, one to engage a key and the other a spring under tension, substantially as specified. I

2. A look comprising-a fixed. cylinder and a movable one, a plurality of S-shaped tumblers formed from a single strip of wire folded to form oppositely-disposed ends which are guided in the movable cylinder, and springs encircling the tumblers to cause the same to move into engagement with the fixed cylinder, substantially as specified.

3. A look comprisinga fixed and a movable cylinder the latter being formed of two and removal of tumblers, a plurality of tumblers guided in holes in the movable cylinlng openings in the-fixed cylinder, said tumblers being formed from a single piece of Wire der, and adapted to register with correspond* 7o to the right. The object of this arrangement parts which are detachable for the insertion bent in such a manner 'as to form two oppoor movable cylinder of a. lock. substantially 1o sitely-disposed loops, and a spiral spring inin the manner shown and described.
